For the choux pastry, boil milk with 7 tablespoons of water, butter and 1 pinch of salt in a pot. Add the flour at once and stir with a wooden spoon until a white layer forms at the bottom of the pot and the dough comes off the bottom as a dumpling. Put the dough into a bowl and immediately stir in 1 egg, let it cool down for about 10 minutes. Then stir the rest of the egg into the dough until a smooth mixture is formed.
For the cream puffs, fill the dough into a piping bag with a large star-shaped spout. Spray 8 small tuffs onto a baking tray lined with baking paper. Bake in a hot oven (electric cooker: 225 °C/circulating air: 200 °C/gas: see manufacturer) for 20-25 minutes. Remove, cut open immediately with scissors and allow to cool.
Wash, clean and quarter the strawberries. Mix with the fruit spread, let it stand for about 1 hour. Whip the cream until stiff and allow the vanilla sugar to trickle in. Stir in liqueur.
Fill vanilla cream into a piping bag with a large star-shaped spout and fill cream puffs with it. Put the lid on top. Dust with icing sugar. Serve with strawberry salad.
Cut open the cream puffs immediately after baking. This allows the moisture to escape and the pastry remains crispy.
